User Interface (UI)
What is User Interface (UI)?
User interface (UI) is the visual and interactive part of a mobile application through which users interact with its features and content. It includes screens, buttons, menus, icons, forms, navigation elements, typography, colors, images, and other interface components. In a no-code app builder, users can create and customize the UI using visual tools and ready-made components without manually programming every interface element.
Why it matters
A clear and consistent user interface helps people understand how to navigate an app, find information, and use its features. UI design also influences the visual identity of a mobile application and works together with user experience (UX) to make interactions understandable and convenient. For businesses creating their own mobile apps, customizable interface elements make it possible to adapt the application to their branding and content.
Example
A business creates a mobile app in an app builder and customizes its interface by adding its logo, brand colors, images, navigation menu, buttons, and different content screens. Customers can then use these interface elements to browse services, open company information, make bookings, and access other app features.
